Patentea'oet. 6, 1914.

To all whom "it may concern:

Be it known that I, WILLIAM F. RAND-ALL, a citizen of the United States, residing-at Philadelphia, 'county of'Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Shoes, of which the following is a full, clear, and exact description, 'reference being had to the accompafnying drawings, which form a part of this specification.

The object of 'my invention is to provide a shoe having a soleadapted primarily to withstand extremes of heat and also 'to 'effectually exclude moisture and resist the abrasive and cutting action of sharp stones.

In certain industries the 'conditions are such as to be destructive of the footwear of the workmen. This is especially true of employees of steel mills and other industrial plants in which conditions of elevated temperature prevail. The workmen are often compelled to walk over heated surfaces and sometimes over red hot cinders and other highly heated substances; and

standing or walking on heated surfaces is .alone effectual to cause speedy disintegration of the leather of the sole and besides oie'rs no adequate. protection to the feet, causing great discomfort to the wearer. Consequently, those working under the Aconditions mentioned frequently tlnd it necessary to improvise some protection for the ordinary leather-sole shoes, which consists in tying some protective material to the sole of the shoe. Such expediente involve loss of time in applying and removal and seriously interfere with comfortable walking and at best are mere makeshifts.

The object of my invention i s to provide a shoe having a sole which, when the shoe is worn under the conditions specified, besides being relatively indestructible, is comfortable and sightly, and may be worn, not only during working hours, but at any other time.

A preferred embodiment of the invention is shown in the drawings in whichl Figure 1 is a side elevation of the shoe and Figs. 2 and 3 sections respectively on the lines .9i-"2 lund 3-3 of Fig. l.

The shoe comprises the usualyamp or upper @,the top Z1 and the sole. The sole lconsists of tlie parts c, d, e, f and g. The part c, which extends from the front 'to the back o'f the shoe, comprises a number of sheets or layers of duck or canvas, which are stitched together and saturated with oil. Lins'ed oil is availablefor the purpose, although other oils are also found serviceable. The part d i's applied under the rear of the part c `and forms, in connection with the rear of part c, the heel.' Like the part c, the part d 'comprises a number of sheets or layers of duck or canvas stitched together and saturated in oil.

Preferably the parts c and 0l are attached t0 the vamp a in the following manner: The lower edge of the vamp, in the part thereof extending from the front of the heel tothe tip of the toe is brought under the edge of a leather insole e, which ee'tends -throughout the length of the shoe, and over the inner edge of a leather welt f, which eX- ten'ds around the margin of the shoe troml opposite sides of the front of the heel. This confined edge of the vamp is nailed, stapled or otherwise secured to and between the insole e and welt The'welt f is secured to the sole c, preferably by stitches l1. extending 'entirely through both members. Between the heel d and sole 0 is inserted a leather welt or skiver g. The heel portion of the vamp a has its outer edge inserted between the insole e and the sole c and is Asecured to both members preferably by means of 'nails y' extendingthrough tli' welt g as well as through the vamp a, insole'c and sole c. The heel member d is secured to the sole c preferably by means of nails i extending throughy both parts and the intermediate welt g.

The leather portions of the sole, particularly the welts f and g, impart the required degree of elasticity to the shoe. The main sole c ci is found to eifectually resist all the deleterious conditions hereinbefore mentioned. A shoe provided with such asole may be placed on a bed of red hot coals and may remain there unti the coals cool and the shoe is found to be substantially uninjured; whereas an ordinary shoe, subjected to these conditions, is to all intents and purposes destroyed, the leather ot the sole crumbling and disintegrating under the high temperature conditions. A shoe embodying my invention is also admirablyu adapted for hot climates, particularly for travel over bot` desert sands or in regions where both extreme heat and great moisture coexist or alternate.

While `the specific way herein set `forth of constructing my improved shoe has ce1'- tain advantages, the invention, in its broader aspect, is not limited thereto.

'Having now fuily described 'myinvention, what I claim and desire to protect by Letters Patent is:

1. A shoe comprising a vamp and an outsole composed of a number of sheets of canvas impregnated with oil and stitched together andsecured to the vamp.

2. A shoe comprising a vamp, a sole member .composed of a number of sheets of canvas im regnated with oil and stitched together an secured to the vamp, and a heel member also composed of anumber of sheets of canvas impregnated with oil and stitched togethe and secured to said sole member.

f 5. A shoe comprising a vamp, a sole member composed of a number of sheets of canvas stitched together and impregnated with oil, a welt between the vamp and said sole member and secured to both, and a heel member'also composed of a number of sheets I' of canvas stitched together and impregnated with oil. and secured to said sole member.
